Gyokko
- Rank: Upper 5
- Status: Eliminated (Season 3)
Gyokko did not look human on the outside. He had mouths instead of eyes; his eyes were located on his hands and forehead. He was very vain regarding his artworks, which often consisted of body parts from his victims. His abilities were based on his pottery skills.
The demon could create porcelain pots in all shapes and sizes. He used the pots as teleportation points to switch places in the blink of an eye. From the pots, he could summon fish that shot needles from their mouths. He could also shape giant octopus tentacles and water prisons from the pots.
In battle, he was threatened so much that he showed his final form, where his body was covered in scales. However, his true body was not enough against Muichiro Tokito, who defeated the demon single-handedly.
Nakime
- Rank: Upper 4
- Status: Alive
Nakime ranked up to Upper 4 after the defeat of Hantengu. She is the demon who plays the Biwa, a Japanese lute, in the background. Even as a human, she played the Biwa, though unsuccessfully. She was transformed into a demon by Muzan.
She ensures that the Upper Kizuki are summoned to meetings and sends them away afterward. And that is also her ability: she can manipulate the Infinity Castle according to her designs. She can also use this offensively by crushing her opponents with created objects.
Akaza
- Rank: Upper 3
- Status: Alive
Akaza has been known as Upper 3 since the Mugen Train Arc. He is a master of unarmed combat and loves to fight against strong opponents. If he respects his opponent, he even offers to turn them into a demon to unleash their full potential. He himself was transformed into a demon by Muzan.
In battle, he can locate his opponent with a compass needle, allowing him to perfectly parry enemy attacks. He can also shoot shockwaves through the air and enhance his strikes with shockwaves. Even his kicks generate powerful shockwaves.
